Anna Kendrick knew she was presenting at the Grammys last weekend, but she had no idea exactly how incredible her night would be. Meeting Beyonce and getting your boobs touched by Katy Perry? Sign us up!

When the Pitch Perfect actress sat down with Conan this week, she shared the story of her amazing celebrity encounters — down to the last finger-banging detail. First up: Beyonce, who Anna has obsessed over on Instagram for as long as we can remember.

“I walked past Beyonce at one point, and because I’m not worthy, I did not look at her,” Anna explained. “We did make a detour past the front row so we could walk past Beyonce.”

Which we would totally do if we were at the Grammys, so it’s not like we blame her.

“We walked past her, and my friend was like, ‘Dude, she was motioning to you, and you just walked past her,’” Anna continued. “And the panic. I didn’t quite know what to do and I was like, ‘Once in a lifetime, just do it.’ I went back, and I was like, ‘I’m so sorry to do this, I just wanted to meet you, you’re such an inspiration.’ And she stood up, she was so nice, and she points to Jay-Z, and she was like, ‘Oh, we just watched you on the Kennedy Center Honors. You were so great, you were so cute in your little red dress.’”

Cue the freak out. “And she said that I had a little red dress, which means that she actually watched it or it means I was having a stroke and I imagined the entire thing!” Anna gushed.

As for Katy? The finger-banging is NBD, these two participate in those kind of activities all the time, as you do when you see an old friend.

“It was a weird night,” Anna shrugged. “In that dress, I was kind of asking for it.”
